VSC7421-04 17-Port Layer 2 Gigabit Ethernet Switch with 12 Fully Integrated Copper PHYs Highlights Microsemi's next-generation switch device delivers the industry's lowest power GbE switching solution. * Supports IEEE 802.3az and green energy efficiency modes with ActiPHYTM and PerfectReachTM VSC7421-04 is the industry's first fully integrated 17-port Gigabit Ethernet switch with 12 copper PHYs in a single package. In conjunction with Microsemi's 4-port VSC8504-03 or VSC8664-03 devices, a 17-port switch can be designed using only two ICs. * Lowest BOM solution requires only two ICs * One QSGMII MAC interface and up to four SGMII ports with 100 Mbps and 1 Gbps fiber support The device leverages Microsemi's 65 nm technology, resulting in one of the most cost-effective and lowest power consumption solutions in the industry. It includes the most advanced Ethernet energy efficiency features for bringing green technology solutions to market. Applications * Unmanaged and Lightly Managed Ethernet switches A rich set of Ethernet switching features, such as Layer 2 forwarding with VLAN and QoS processing, enables the delivery of differentiated services. The VSC7421-04 device contains an 8051 CPU for light management of the switch. * Industrial switches and routers * Customer premises equipment (CPE) and outdoor equipment * VPN, firewall, and UTM appliances A comprehensive application software package is provided for LED control, loop indication, device overheat protection, and other enhanced functions.
